  1. 1. Hydrological catchment analysis from characterisation of organic matter in stream water

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Hannes Berg Wiklund; [2020-02-05]
    Keywords : Organic matter; Time-of-flight mass spectrometry; aquatic chemistry; catchment hydrology;

    Abstract : Organic matter (OM) in aquatic systems is a complex field which have rapidly developed duringthe last decade due to the introduction of high resolution mass spectrometers. The compositionof OM in the aquatic environment is directly dependent on factors such as oxygen supply, pHand the flow rate in the local system. READ MORE

  3. 3. Experimental studies at CERN-nTOF of the 230Th(n,f) reaction

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Felicia Lapinski; [2020]
    Keywords : fission; neutron induced fission; fission cross section; fission fragment angular distribution; thorium;

    Abstract : This work investigates the feasibility to perform an experiment at CERN n_TOF to study the fission cross section and fission fragment angular distribution (FFAD) of the 230Th(n,f) reaction. An analysis of fission fragment energy losses in the experimental target resulted in a choice of target thickness of 0. READ MORE

  4. 4. Analyses of microbial community in nutrient solution with biofertilizer and risk assessment of establishment of pathogens

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Julia Södergren; [2020]
    Keywords : Biofertilizer; hydroponic; 16S rRNa sequencing; challenge testing; calorimetry; applied microbiology; teknisk mikrobiologi; Agriculture and Food Sciences; Technology and Engineering;

    Abstract : The societal interest for a more sustainable and circular food production is increasing. Hydroponic farming is an alternative way of growing vegetables that can bring farming into urban environments, reducing long transports of food. In parallel, the focus in waste treatment is being more directed toward resource recovery. READ MORE

  5. 5. Optimization of a Methodology for Cell Based Untargeted Metabolomics with UHPLC-Q-ToF-MS

    University essay from Uppsala universitet/Analytisk farmaceutisk kemi

    Author : Jens Westerinen; [2020]
    Keywords : ;

    Abstract : Metabolomics is the study of small molecules (molecular weight < 1500 Da) in a biological system and can provide relevant information about endpoints of biochemical pathways by establishing metabolic profiles for different sample cohorts and comparing these through multivariate data analysis. The aim of this thesis was to establish and test a suitable methodology for cell-based untargeted metabolomics, utilizing UHPLC-MS. READ MORE
